Sustainable Homes (project based learning)

This post describes a module of the Connections to the Land unit. A project based learning approach (PBL) was used as a way of bridging the students growing understanding of our ecological connection to the land together with our real everyday existence. Students were asked to design and build model homes and were  informed the homes would be tested by three measures of sustainability.

1 Water: how much water could the house catch and retain. This was tested by poring one litre of water over the house using a shower hose, water was directed from the roof to measuring cylinders via the student designed guttering system. Also ensuring the home was waterproof helped maintain the structural integrity of the home in the final test.

2 Temperature: does insulation help reduce energy use? Could a home be kept cooler by better design? Data-loggers and temperatures probes were deployed and temperature verses time graphs produced.

3 Structural integrity: the homes were lined up on the oval and using a leaf blower we carried out wind tests… none were quite up to the test.

The students were given a price list of materials and 100 credits to purchase what they required. Most opted to use prefabricated cardboard houses sourced from theboxman.com. (See an outline of the information provided to student  here.) Some students loved the ‘shopping’ element of the task and spent considerable time deciding what they would ‘purchase’ while others spent more time ‘tinkering’ with different solutions to the three problems that had been presented.

Overall students thinking was pushed deeper by trying to design solutions to complex real world problems. Problems they will all need to face as our society learns to live in a sustainable way. The groups that produced better, more sustainable homes, spent more time thinking, planning, tinkering, testing, redesign and rebuilding. Good design is often not the first solution you try.
